What we have accomplished

Several configuration fixes and dependency version upgrades got completed in the last three weeks!

🥳 Axon now supports rpc calls to get block and proof by block ID! ‣

👌🏻 We’ve finished the initial development of several modules for Axon Spark, the kicker for Axon.

• Storage module has been developed and merged feat(storage): add smt and relational storage spark#8. It includes both the smt and sqlite to store the staking information.
  • smt: stores staker, delegator, reward and proposal information of all epochs for axon chain.
  • sqlite: stores all axon staking, delegating, withdrawing transaction history. It is worth notice that the transactions happen on CKB.
• Query module has been developed and merged feat(api): add history status api module spark#10. It defines the query APIs that handle the requests from the frontend.
• Staking transaction structure has been constructed feat: fill in transaction data spark#9. It puts together the data required to construct the staking transaction.

🧑‍🎨 On the frontend side, we’ve closed several rounds of UI design.

What we are doing?

• Intensively developing all kinds of transactions and related contracts for staking, delegating, and withdrawing.

• Finalizing our website design and development.

• Then we will be conducting integrated tests and preparing for the release afterwards!

Stay tuned!

had one question regarding this: "smt: stores staker, delegator, reward and proposal information of all epochs for axon chain."

is this data structure append-only?

Yes, the data is append only.

what's the advantage to using SMT over MMR?

[driftluo]

Strictly speaking, stores staker, delegate, and reward are not pure append-only data. They can be added or deleted at will during the unfinished period of an epoch. Only when the epoch is over and the settlement is completed, can it be regarded as real freeze data. mmr is friendly to append-only data, but it cannot be added or deleted at will

thanks for explaining @driftluo this does make the decision clearer for me
